Advanced Applications of Heavy Vehicle EDR Data
This class will provide the student with the skills, knowledge, and abilities to interpret, analyze and apply Heavy Vehicle Event Data Recorder (HVEDR) data in real world applications. This course has been designed to build on the concepts presented in the SAE course Accessing and Interpreting Heavy Vehicle Event Data Recorders (ID# C1022). Advanced topics will include associating HVEDR data with collision events through timestamps, odometer logs, and data signatures, validating HVEDR speed data using specified vehicle parameters, performing time and distance analyses using HVEDR data, and correlating HVEDR data to physical evidence from the vehicle and roadway. These higher-level techniques and applications are intended to increase student understanding of applying HVEDR data to a crash reconstruction analysis.
What Will You Learn
Upon completion of this course, participants will be able to:
- Associate HVEDR information to real world crashes based on vehicle configurations, parameters, and incident specific data using timestamps, odometers, logs, and physical evidence
- Evaluate and compare multiple data sets from different vehicle systems (either OEM or aftermarket)
- Establish area of impact and vehicle approach considerations based on HVEDR data and scene measurements from real world examples
- Calculate speed, time and distance based on HVEDR data in combination with the available physical evidence
- Employ advanced analytical techniques for HVEDR information based on peer reviewed research and SAE technical publications
- Document and present HVEDR investigative findings for use in criminal or civil proceedings
Is This Course For You
Engineers and accident reconstructionists who document and analyze crashes involving heavy trucks, tractor-trailers, buses, etc. who need to successfully apply both standard accident reconstruction methodologies and specialized techniques to truck crash analysis will find this course valuable.
